Blood Test Clues Before Symptoms? Wild!

Scientists just found that a blood protein called GFAP is higher in people with hereditary transthyretin amyloidosis (ATTRv)—even before they show symptoms! Another marker, NfL, only goes up once symptoms start. Basically, a simple blood test could help spot this rare nerve disease way earlier than we thought. Oh, and women naturally have more GFAP, so that’s gotta be factored in. Medical mysteries, am I right? #MedicalNews #RareDisease #ScienceUpdate #Biomarkers #HealthDiscovery #Health
